Imaging materials. Processed vesicular photographic film. Specifications for stability

PUBLISH DATE 2002
PAGES 32
BSI BS ISO 18912:2002

This International Standard establishes specifications for the stability of polyester-base safety film which has a heat-processed vesicular photographic image formed by nitrogen bubbles. It is applicable only to vesicular photographic film intended and used as LE-10 and LE-100 storage copies, which shall be stored in accordance with ISO 18902 and ISO 18911.

This document characterizes only the inherent keeping behaviour of the film. However, the suitability of a film record after extended storage depends on both the inherent ageing characteristics of the film and the original image quality. The latter is discussed in annex C.

This International Standard is applicable to photographic film in which the image layer is a discrete layer attached to a transparent support, and it applies to roll film and sheet film.

This International Standard is not applicable to vesicular film records intended and used as “work” or “use” copies as discussed in annex B.

The effects of heat and pressure are discussed in annex D and those of high humidity in annex E.
